A one-name study is a collection of living persons (''address, phone'') and other biographical (''census'') data about persons sharing a particular surname or patronymic name based on the name of one's father, grandfather or an even earlier male ancestor. Some researchers are satisfied to collect information and reconstructed '''lineages'''. By distinct '''branches''', we distinct '''family groups''' which do not appear to have a direct connection. The data of the different family trees can be
manipuled by “FamilyGroups” which distinguish the '''unrelated groups'''.
To select each family group, one different marker is added by group (homogenous related branches with one common ancestor). The better use of this marker is in a “Identification Number” ( or "ID") attribute of each person and one value by 'family' group.
